Introducing rooster to hens

Hello, we have 12 hens (black & red stars) and we would like to introduce a RIR rooster to them. What are the recommendations for introducing a new roo to a flock of hens? Our girls are 28wo and the roo is 18mo. Should we seperate them in the pin for a few weeks? Any advice please!!

Your hens are full size, and if you don't have another pen, put him in the pen with your girls. A few feathers might fly, but it will settle down in a day or two.

I am assuming that the roo is healthy, comes from a place that looks good. If you do it my way you are risking introducing a disease to the flock, but it is not a real large flock, but it is a risk, and if the thought of losing some birds scares you, then don't risk it.

Most people do not have enough space to do a proper quarantine, and if you don't do quarantine properly, you are wasting your time pretending to do quarantine.
